阿瓦提丰收灌区无排水条件下葡萄滴灌土壤水盐运移规律研究

Study on Movement Law of Water and Salt in Soil Under Condition of Drip Irrigation and without Drainage in Awati Irrigation Regions,Xinjiang

以新疆阿瓦提县丰收灌区为例,对葡萄滴灌的土壤盐分运移进行了监测研究,结果表明:干旱区无排水条件下,宽行葡萄实施滴灌灌溉,干排盐功能和压盐、抑盐作用明显。在土壤盐分含量较高的干旱区引用地面水实施滴灌,系统的设计必须考虑压盐、抑盐水量,同时采用高频滴灌制度,确保供水保证率,才能达到林果业可持续发展的目的。

Monitoring analysis was conducted on movement law of water and salt in soil with drip irriga tion for grape in Awati irrigation region,Xinjiang. The experimental result demostrated that desalting function and dilution soil salt content were not remarkable,wben there was no irrigation condition in arid region,the drip irrigation was applied to wide row grape. The drip irrigation was applied to arid region with surface water of high salt content in the soil. The water of dilution soil salt content should be fully considered when system design was made. At the same time, high frequency drip irrigation regime should be applied to sufficiently supply water to ensure the sustainable development of fruit trees.
